A tractor-trailer crash on Interstate 35 Thursday afternoon briefly blocked both lanes of traffic near exit 205 in San Marcos, forcing first responders to divert motorists onto the access roads to bypass the crash.

By around 3:30 p.m. Thursday, crews were able to open two lanes of traffic southbound and one northbound. Motorists traveling in both directions are advised to enter the access roads prior to exit 205 to avoid heavy congestion at the scene.

The tractor-trailer lost control at it was traveling northbound on IH-35 and struck a utility pole, knocking the pole and lines down across both the northbound and southbound lanes.

Clean-up crews have been called to contain a fuel spill from the semi’s ruptured fuel tanks, which were nearly full when the crash occurred. Fire officials say there is no immediate fire danger, but they are working quickly to contain the spill before the rain washes it into the environment.

The driver was transported with minor injuries. Emergency units are still on the scene.
